Abstract
A display panel is described that includes a picture element controllable by an active matrix drive comprising at least one structural element (a), wherein the at least one structural element (a) comprises a plurality of sub-units (b1, b2, b3) whose electrical connectivity (c1, c2, c3) is alterable for repairing of an electrical malformation related to the structural element (a).
Claims18
A display panel comprising:
- a picture element controllable by an active matrix drive comprising at least one structural element,
- wherein the at least one structural element comprises a plurality of sub-units, electrical connectivity of the plurality of sub-units being alterable for repairing an electrical malformation related to the at least one structural element.
A method of manufacturing a display panel comprising a picture element controllable by an active matrix drive comprising at least one structural element, the method comprising:
- creating the active matrix drive as a set of layers including one or more conductive layers;
- patterning the one or more conductive layers to define electrical connections for structural elements of the active matrix drive;
- and
- wherein the creating and patterning steps result in providing the at least one structural element with at least one redundant unit.
A method of repairing a defective electrical connection of a display panel comprising an active matrix drive for a picture element, said active matrix comprising structural elements including redundant units, the method comprising:
- detecting the defective electrical connection of the active matrix drive including redundant units;
- and
- selectively altering electrical connectivity of the redundant unit for repairing the defective electrical connection.
